    Subject[PATCH AUTOSEL for 4.9 124/156] Ib/hfi1: Return actual operational VLs in port info query
    Date
    From: Patel Jay P <jay.p.patel@intel.com>

    [ Upstream commit 00f9203119dd2774564407c7a67b17d81916298b ]

    __subn_get_opa_portinfo stores value returned by hfi1_get_ib_cfg() as
    operational vls. hfi1_get_ib_cfg() returns vls_operational field in
    hfi1_pportdata. The problem with this is that the value is always equal
    to vls_supported field in hfi1_pportdata.

    The logic to calculate operational_vls is to set value passed by FM
    (in __subn_set_opa_portinfo routine). If no value is passed then
    default value is stored in operational_vls.

    Field actual_vls_operational is calculated on the basis of buffer
    control table. Hence, modifying hfi1_get_ib_cfg() to return
    actual_operational_vls when used with HFI1_IB_CFG_OP_VLS parameter
